  1. Data limitation

    No geometry is recorded for 2007 Trek Pilot 2.1 WSD and 2008 Trek Pilot 2.1 WSD.

  2. Gearing

    2008 Trek Pilot 2.1 WSD has a 7% lower climbing ratio than 2007 Trek Pilot 2.1 WSD.

    A lower ratio gives more mechanical advantage; rear-wheel rollout determines distance per crank turn.

How it works

Ratio = front teeth ÷ rear teeth. Hub gears also include the hub’s internal ratio. A 400% range means the highest ratio is four times the lowest.

Speeds are estimates from tire size and pedal cadence. Actual speeds vary.
